Bought a 1500W 110/220 up/down transformer at Fry's Electronics for
about 90 bucks a few years ago. Worth checking.

Magellans, the travel supply company, sells transformers between 110V
and
220V. They come in all sizes. The one to handle 1000 Watts weighs 18
pounds and costs a little over $100. I used one just like that in the
WRTC
20000 in Slovenia. It worked flawlessly.
